Bed bugs are persistent pests that can bring pain and anxiety for individuals.

Their tiny size, nocturnal nature, and ability to hide in various nooks and crannies make them challenging to eliminate. In the quest to find effective solutions, people often wonder if WD-40, a popular multi-purpose lubricant, can get rid of these pests.

In this article, we get into the topic of bed bugs and WD-40, examining whether this household product holds any potential as a remedy for these bothersome insects. Let’s explore the facts and separate reality from misconceptions.


How do bed bugs infest homes?

They can infest homes through various means, including:

  • Hitchhiking:  They are skilled hitchhikers and can latch onto luggage, clothing, or furniture. They can be unknowingly brought into homes after staying in infested hotels, using public transportation, or visiting infested areas.
  • Second hand furniture and items: Infested furniture, mattresses, or clothing purchased from thrift stores or acquired from friends and family can introduce bed bugs into a home.
  • Shared living spaces: They can easily travel between adjacent apartments, condominiums, or shared living spaces through cracks, electrical outlets, or pipes.
  • Visitors: Guests who unknowingly carry these insects on their belongings can introduce them into a home, especially if they have recently stayed in an infested location.


It is important to be vigilant when traveling, acquiring second hand items, or having guests to minimize the risk of bed bug infestations.


Are bed bugs visible to the naked eye?

Yes, they are. Adult bed bugs are approximately the size of an apple seed, ranging from 4 to 5 millimeters in length. They have a flat, oval-shaped body, and their color varies depending on their feeding status. When unfed, they appear translucent or light brown, while after feeding, they become engorged and turn reddish-brown. Although they can be challenging to spot due to their ability to hide in tiny cracks and crevices, careful inspection of infested areas can help you detect their presence.


Are bed bugs only found in beds?

They are not only found in beds. While they are commonly associated with beds and mattresses due to their preference for feeding on human blood during sleep, they can infest various other areas in a home. They can hide in cracks and crevices of furniture, walls, baseboards, carpets, curtains, electrical outlets, and even luggage or clothing. They have the ability to move and spread throughout a dwelling, seeking harborage close to their hosts. It’s important to inspect and treat all potential hiding spots when dealing with a bed bug infestation.


What is WD-40?

WD-40 is a widely recognized brand of multi-purpose lubricant and penetrating oil. The name “WD-40” stands for “Water Displacement, 40th formula,” indicating its original purpose as a water displacement compound. It was developed in 1953 by a chemist named Norm Larsen while working for the Rocket Chemical Company.

WD-40 has versatile applications and has become popular for a wide range of uses beyond its original intention. You can use it as a lubricant to reduce friction, prevent rust and corrosion, and loosen stuck or squeaky parts. Its formula consists of various petroleum-based solvents and lubricants that make it effective for tasks such as freeing up rusted bolts, lubricating hinges and door locks, protecting tools from moisture, and cleaning and polishing surfaces.

In addition to its lubricating properties, you can use WD-40 to remove adhesives, grease, and tar stains from surfaces. It is available in aerosol cans with a small red and blue logo, and the product has gained a reputation for being a handy household item and an essential tool in many industries. However, it’s important to note that WD-40 may not be suitable for all applications, and it’s advisable to follow the instructions and use it in accordance with the manufacturer’s recommendations.


Will WD-40 keep Bed Bugs away?

No, WD-40 is not an effective solution for keeping bed bugs away. WD-40 is primarily a lubricant and penetrating oil and does not possess properties that repel or eliminate bed bugs. They are small parasitic insects that feed on the blood of humans and animals, and their presence in a home typically requires specialized pest control methods for eradication.
